Saw this in a box lot at a local auction last Saturday. Thought for a second there that I might be going home with a Millers Falls plane. A second look cured me of that notion. This one has (had) red plastic handles. So, how do you get a handle to look like this? http://i1358.photobucket.com/albums/q780/gctool/20140823_085130_zpsef11 ec0d.jpg">http://i1358.photobucket.com/albums/q780/gctool/20140823_085130_zpsef1 1ec0d.jpg And on a brighter note, I ended getting something that I don't remember seeing before. Probably cause I never looked. A two yard wooden advertising yard stick. I was the only bidder at a buck, so I guess I left some money on the table. Measured it at home, and found it to be within 1/16" full length. I expect it's accurate on day out of the year. No idea what I'm gonna do with it, but it is different. Gary Caron York, PA |

Plastics are very diverse, and I don't know which one was used by Millers' Falls. However, the oldest and most common was cellulose nitrate (celluloid), and Ricky Jay published a fascinating book on the decay of his collection of cellulose nitrate dice. http://www.amazon.com/Dice-Deception-Fate-Rotten- Luck/dp/1593720300">http://www.amazon.com/Dice-Deception-Fate-Rotten- Luck/dp/1593720300 http://www .npr.org/templates/story/story.php?storyId=893954 Some of the information is to be found on the Museum of Jurassic Technology website, though my memory of the book is much more vivid than what is on the website: http://www.mjt.org/exhi bits/rickyjay/rjay.html http://www.mjt.org/exh ibits/rickyjay/rjay2.html Jay's dice are mostly celluloid, which dates back to the 1860s. Although I doubt celluloid would have been up-to-date enough for Millers Falls, its manner of decay is similar to a number of other plastics, and gross symptoms of the decay can be similar. Celluloid is a physical mixture of cellulose nitrate (also known as guncotton, the dominant high explosive of WWI) and camphor as plasticizer. Over time the camphor evaporates out of the celluloid, causing it to shrink and get brittle. The cellulose nitrate polymer breaks down, and in breaking down releases nitric acid, which accelerates the breakdown, sometimes explosively. Later plastics used less volatile plasticizers for a physical mixture, or actually used an "internally plasticized copolymer" where the polumer chain is runs of the plasticizer alternating with runs of the basic polymer. And later plastics used polymers that broke down less quickly and less explosively than cellulose nitrate. Even so, many plastics are similar to celluloid in make-up, decay, and physical symptoms of decay. If I had to make a guess I would say that MF handles are most likely cellulose acetate, which breaks down a lot like celluloid only slower, but this is a long way from my real competence and I'm pretty much guessing there.

Could be > degradation from poorly made polymer. > I agree...if I might offer a suggestion. Once upon a time someone built a garage for their model A. They put windows in the end because it is cool. In the end of it they placed some long pine boards for a series of shelves and a workbench of sorts. This was the sort of pine that was commonplace then straight grained and clear, I would kill to be able to buy such pine at the lumberyard today. However over the years a veritable amount of crap was accumulated (as my garage attests to) including in that some woodworking tools. These tools along with stiff paint brushes and broken shovels and hedge trimmers made up the accumulation. At some point in time someone removed the plane from the shelf along with a considerable amount of dust and without any tuning processed to use it on a pinewood derby or to trim a door. Unpleased with its performance they tossed it on the bench and walked away. Spring to summer to fall to winter. The sun rises and sets. The tote is exposed to light and darkness. The knob is protected by a mountain of garden hose that covers it for years. The tote witnesses the sun rising and setting. The heat of summer the cold of winter. That's what happened. 123...GO!
